WAGON-BRAKE.

ySPECIFICATION forming part of Letters Patent No. 441,008, dated November 18, 1 890.

Application filed September 24, 1890. Serial No. 366,000. (No model.)A

To all whom it muy concern:

lowing is a full, clear, and exact description of the invention, which will enable othersy skilled in the art to which it appertains to make and use the saine, reference beingI had to the accompanying drawings, which form a part of this specification, and in which- My invention relates to improvements in wagon-brakes.

The object of my invention is to provide a simple and economical construction of Wagonbrake which shall be efficient and reliable in operation and which may be set or the brakeshoes be brought into contact with the wheels bya person occupying the vehicle or from the rear or sides bya person outside the same, as may be found desirable.

The invention consists in the novel construction and combination of parts hereinafter fully described, and specifically pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view of the rear portion of a wagon with my improved brake mechanism applied thereto. Fig. 2 is a side view of the same, the wheel being broken away. Fig. 3 is a longitudinal sectional view, the wheels being removed. Fig. 4f is a detail view of one of the collars on the operating-shaft. Fig. 5 is a Viewy of the rear portion of the rack-bar connected with the brakebeam, showing the slot in same.

In the said drawings, the reference-numeral 1 designates the wheels; 2, the axle; 3, the reach, and 4 the hounds,which may be of any ordinary construction.

The brake-beam is designated by the numeral 5, and consists of a transverse bar, provided with shoes 6, which are adapted to engage with the tires of the wheels, as usual. Secured to this beam is a rearwardly-extending bar 7, having a number of rackteeth 8 near its rear end. Abar 9 is also secured to the beam 5, which extends rearwardly over the cross-bar 10, connecting the hou nds,where it is bent downwardly and secured to bar 7. Journaled in bearings 12 in the hounds 4 is a transverse operating bar or shaft 13, provided with handles 14 at each end, by means of which it may be oscillated. Upon this shaft is loosely mounted a pinion or segment 15, having two oppositely-projecting studs 16, which is free to rotate thereon, and which engages with the rack-teeth on bar 7. Located upon each side of this pinion or segment is a collar 17 ,which is rigidly secured to the shaft 13. These collars are each provided with an extension 1S, having an inwardly-projecting lug 19, which lugs are engaged by the studs 1G on the pinion or segment. The rear end of the bar 7 is formed with an upwardly and rearwardly projecting extension 20, 'which passes through an aperture in the box 2l, which is carried by the axle and which supports the wagon-body. This extension is provided with an elongated slot 22,within which Works a stud 23, carried by the short arm of an elbow-lever 24, pivoted in a lug 25, secured to said box 21. The numeral 26 designates a segrnent-bar secured to the box 21, and provided with a series of teeth to engage with lever 23 and hold it in place.

The numeral 27 designates a spring interposed between the brake-bea1n and the crossbar 10. The tendency of the spring is to force the beam forward and release the shoes from contact with the wheels.

The operation is as follows: When it is desired to actuate the brakes from the vehicle, the operator pulls the handles of the shaft 13 forwardly, turning said shaft and causing the lugs 19 on the collars 17 to engage with the studs 16 on the pinion or segment 15, whereby the latter is rotated or oscillated, and by means of the rack-teeth on the bar 7, with which it engages, the said bar is drawn backward, carrying with it the brake-beam and shoes and braking the wheels. By means of the slot 22 in the extension 2O the bar 7 can be reciprocated wit-hout actuating the lever or causing it to wabble, as the stud 23 thereon will play therein. A reversal of the operation will release the brakes. Vhen it is desired to operate the brakes from the rear of the wagon, the opera-tor grasps the lever 24 and moves it outwardly, causing the lug 25 to actuate the bar 7 and set the brakes. The pinion 15, being loose on shaft 13,Will be rotated by the rack teeth Without rotating the shaft, thereby allowing the bar 7 to freely move.

From the above it will be seen that I provide a very efficient mechanism for braking the wheels of Wagons and other vehicles, which can be operated either by the occupant of the vehicle or by a person on the outside, or both.

It may sometimes be found desirable to dispense with the devices for actuating the brakes from the rear. In this case the pinion or segment should be rigid or fastened rigidly on the shaft 13.

Having thus described my invention, what I lclaim isf-- 1. The combination, with a Wagon, of the brake-beam and shoes, the rearwardly-extending bar secured to said beam and provided With rackteeth, the transverse rockshaft having collars rigidly fixed thereon and provided With inwardly-projecting lugs, and the pinion or segment loosely mounted on said shaft and provided with oppositely-pro jecting studs adapted to engagewith the lugs on the collars, substantially as described.

2. The combination, with a Wagon, ot the brake-beam and shoes, the rearward1yex tending bar secured to said beam and-provided with rack-.teeth with an elongated slot,

the transverse rock-bar having collars rigidly iixed thereon provided with inwardly-projecting lugs, the pinion or segment loosely mounted in said shaft and having opposite outwardly-extending studs, and the pivoted elbow-lever having a stud engaging in the slot in the rearwardly-extending bar, substantially as described.

3. In a Wagon, the combination, with the reach, the hounds, thebrake-beam and shoes, the bar connecting the hounds, and the spring interposed between said bar and the beam, of the rearwardly-extending bar having rackteeth, and an extension having an elongated slot, the bar secured to the brake-beam and extending over the connecting-bar and secured to said rearwardly-extending bar, the transverse rock-bar having xed collars with inwardly-projecting lugs, the pinion loosely mounted in said shaft and provided with outwardly-projecting studs, the elbow-lever having a stud engaging with the slot in the said extension, and a segment having teeth to en gage with said lever and hold it in place, substantially as described.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two Witnesses.
